Line charts

Temperature over time

A line chart displays information as a series of data points connected by straight line segments. In this case the data points reffer to temperature values over the experience time period of measurements.

In the horizontal axis (x-axis) it is represented the time period, that goes from mid January to begining of May 2022.

In the vertical axis (y-axis) it is represented the Temperature in Celsius degrees. Most of values are around 20°. But, arroubd February 13thm there are certain values of temperature around 0°. These values that differ so much from the majority of values are called outlayers.

Oxygen concentration over time

Here we show again a line chart. This time in the horizontal axis (x-axis) we represent the concentration of oxygen in the water. And in the vertical axis (y-axis) the same pariod of time represented in the above line chart.

What about Oxygen concentration?

• About Oxygen >>
• What it means concentration? In chemistry, the fraction of an element (in our case, Oxygen) dissolved in or carried by a fluid. More in /a> wikipedia >>
• Why we are measuring the concentration of oxygen in the weter? The concentratiuon of oxygen in water is proportional to the amount of water from the sea (salted) mixed with the water from the wetlands (not salted).
